When the rocket is launched, the gas flow rate is 2800 m/s, and the local instantaneous high temperature is above 2000 ℃, and high-speed shock waves and reflected waves are generated at the same time.
In order to develop a new type of high-performance refractory for aerospace with excellent performance, safety, reliability, and excellent construction performance, BJJY Refractory Technology Group Corporation and China Aerospace Science and Technology Group formed a special R&D team to continuously discuss improvement plans, assiduously research, and countless experiments Finally, the new materials developed have been greatly improved in terms of material composition, high temperature resistance, high temperature erosion resistance, stability, and service life. Up to now, BBMG refractories has provided refractory material supply or construction services for all four satellite launch centers in Jiuquan, Taiyuan, Xichang, and Wenchang. In the future, it will continue to consolidate its leading position in refractory materials in the aerospace field and help China's aerospace dream .
